Table 10–2: Installing the KZPSA-BB or KZPBA-CB for Radial Connection
to a DWZZH UltraSCSI Hub (cont.)
Step
Action Refer to:
2
Power down the system. Install a KZPSA-BB
PCI-to-SCSI adapter or KZPBA-CB UltraSCSI host
adapter in the PCI slot corresponding to the logical
bus to be used for the shared SCSI bus. Ensure
that the number of adapters are within limits for
the system, and that the placement is acceptable.

3
Install a BN38C cable between the KZPBA-BB
or KZPBA-CB UltraSCSI host adapter
and a DWZZH port.

_____________________ Notes _____________________
The maximum length of a SCSI bus segment is 25 meters, including the
bus length internal to the adapter and storage devices.
One end of the BN38C cable is 68-pin high density. The other end is
68-pin VHDCI. The DWZZH accepts the 68-pin VHDCI connector.
The number of member systems in the cluster has to be one less than
the number of DWZZH ports.
4
Power up the system, and update the system
SRM console firmware and KZPSA-BB host
bus adapter firmware from the latest Alpha
Systems Firmware Update CD-ROM.
Firmware release
notes for the system
(Section 4.2) and
Section 10.1.4.5
______________________ Note ______________________
The SRM console firmware includes the ISP1020/1040-based PCI
option firmware, which includes the KZPBA-CB. When you update the
SRM console firmware, you are enabling the KZPBA-CB firmware to
be updated. On a powerup reset, the SRM console loads KZPBA-CB
adapter firmware from the console system flash ROM into NVRAM for
all Qlogic ISP1020/1040-based PCI options, including the KZPBA-CB
PCI-to-Ultra SCSI adapter.
5
Use the show config and show device console
commands to display the installed devices
and information about the KZPSA-BBs or
KZPBA-CBs on the AlphaServer systems. Look
for KZPSA or pk* in the display to determine
which devices are KZPSA-BBs. Look for QLogic
ISP1020 in the show config display and
isp in the show device display to determine
which devices are KZPBA-CBs.
